Repair leaking felt roof seams

[FergusMacdonald]

Hello.
Have a flat roof on my garage and the seams of the felt are leaking - they're not well stuck together any more. I tried painting with flexacryl - acrylic waterproofing which helped, but hasn't solved the problem. I also bought some roofers seal in a tube and was thinking about pushing that under the overlaps to seal them together.
Ultimately could put bitumen over the whole roof but wondering if there's an easier method.

Thanks.

You could prime the joints and cover with strips of mineral felt stuck down with cold fix bitumen, better job would be 4mm torch on felt but you have to be careful using roofing torches.

Just apply more of the same stuff for the time being! no point it being in the tin!
